Description
The WIM MC25KVA / DN25N is a 25 kVA single-phase spot welder with a digital controller, for resistance welding sheet and light structural steel in fabrication shops, metal furniture production and general repair work.
Key Features
- Digital DN25N controller — weld time, current and squeeze are set as numbers and repeat exactly, instead of being dialled in by feel.
- Silicon-controlled rectifier drive — solid-state switching, no contactor to burn out under production duty.
- 0.5 cycle sampling, 1 cycle response — the controller corrects within a single mains cycle, so weld nuggets stay consistent as the tips wear.
- 25 kVA on a single-phase 380 V supply — useful output without a three-phase installation.
- Under 15 W control loss — the electronics run cool, which matters in an unconditioned workshop.
